STATES PATENT OFFICE.

nniimnapxnimrcn; on BIRMINGHAM, ALABAMA, ASSIGNOB, T0 LESTER E. annmr, 4 on SOUTHAMPTON, NEW YORK.

Be it known that I, DANIEL A. Hnmuorr, a citizen of the United Stats, residing at Birmingham, in the county of J efierson and State of Alabama, have invented new anduseful Improvements in Cellular Walls for Sewage-Disposal Apparatus, of'which the following is a specification. a My. 'nvention relates to certain novelimprovements in an. earth inclosed-apparatus for the disposal of sewage.

The particular feature of my invention which forms the subject matter of this application, is the' nanner of forming the walls of the pit or'cavity in which the sewage is received for disposaland distribution into the. surroundinggearth.

My object is toparticularly strengthen the walls of-the cavity so asto prevent any tendency toucave inand-at the'same time to do this without interferin with .the ready absorption by the surrounding earth of the liquids of the sewage in the tank. To this end I-line the walls of the earth cavity with ordinary hollow tiling, such, for instance, as the hollow tiles used for partitions 'in buildings, and. I arrange these radially'so that the sewage will flow freely through them into the surrounding earth. I have found that moss serves as a very effective filling for the hollow tile and may also be used in the bacteria bed in combination with material such as furnace slag, broken brickbats and broken rock.

In my preferred embodiment my invention is illustrated in connection with a septic tank equipment which however forms no part of my present invention.

In Figure 1 the pit or cavity for the sewage is shown in vertical cross sectional elevation. Fig. 2 is a plan view of Fig. 1

- with the cover reinoved.

Similar reference numerals refer to similar parts throughout the drawings, The sewage to be treated is shown d18- charged into a tank 1 through a stack 2 and pipe 3, which discharges into an inlet duct 20 connected to a dash-board 5. The walls of tank 1 are preferably formed of concrete.

The sewage flows out through an outlet duot 21 into the receptacle from whiclr-it is desired to distribute it into the surrounding.

withthe said slag or b'rick bats, .thewhole be advantageously used by intermingling it forming a porous bed -through which the sewage filters to .the walls of the earth cavity. I provide a concrete top 17 extending over the earth cavity and .it may be formed integral-with the inner tank 1 whenthe latter is used.

In order to .support the side wall of the earth cavityforming the sewage receptacle -to prevent its caving in, I provide a wall built up of hollow-tiles 16, preferably the ordinary type of tile used in buildings for forming partitions, and I arrange thes'e tiles with the longitudinalapertures or cells disposed outwardly or radially. I preferably fill these apertures with, moss or other porous filling 14 to prevent the earth, when wet, from working n through the tiles into the tank or cavity. These tiles or cellular units not'only form a firm support for the outer edge of he cover 17 for the apparatus,

but they interfere to no appreciable extent with the outflow of the scwage into the surroundlng earth. a

No claim is made in this application to 'any part of the im'ention disclosed except the integral cellular units which are laidin tiers to form the surrounding walls of the earth inclosed sewage receptacle and are so arranged that-their cells will extend from the inner to the outer surface of the cellular wall, said cells being provided, if desired, with a porous filling. All other features relating to the septic treatment of the sewage form the subject matter of my pending application, Serial No. 560,852, filed May l2t 1910. The earth inclosed sewage receptacle'may be of the septic or the ordinary cess pool type.

Having thus described my invention,

what I claim as new and desire to secure by Letters Patent, is :T

1 Ancarth inclosed sewage recc itacle having a wall built up of integral ce lular units laid upon each other in tiers so that :the cellswill'extend fromthe inner to the outer surface of said wall.

2.;An earth inclosed sewage receptacle having a wall built of integral cellular units laid upon each other in tiers so that the cells will extend from the inner to the outer surface of -said wall, and a porous filling'insorted in the-cells of said units, substantially as described.

3. An earth inclosed sewage receptacle having a wall built of integral cellular units laid upon each other in tiers so that the cells will extend from the inner to the outer sur 5 face of said wall, and a fibrous filling inserted. in the cells of said units, substantially as described.

' 4.' An earth inclosed sewage receptacle having a wall built of integral cellular units 10 laid upon each otherin tiers so that the cells 4 will extend from the inner to the outer surfaceof said wall, and a. filling of moss inserted in the cells, of said units, substantially as described.

In testimony whereof I have hereunto set 15 my hand in presence of two subscribing witnesses. j DANIEL A. HELMICH.
